Patented Apr. 2, 1912.

Be it known that we, HIRAM'HYDE and JACK GAGE, citizens ofthe United States, residing at Geneseo, in the county "of Rlce, State of Kansas, have invented a new and useful Hydrocarbon-Engine, of which the following is a specification.

This invention relates to hydrocarbon engines and more particularly to means for feedin fuel thereto, said fuel feeding means4 being 1n the form of an attachment which can be readily applied to ordinary types of hydrocarbon enginesand which, when thus fuel requiring the application'of heat for the purpose of vaporizing it. 1

A further object is to provide fuel feeding means in' which both the hydrocarbon fuel oughlyheated without 'the necessity of uti-y lizing a burner for that purpose. i 'Wlth theforegoing and other ob]ects 1n roceeds, the invention resides in the com- Eination and arrangement of parts and in the details of construction .hereinafter described and claimed, it being understood invent-ion herein disclosed can be made departing from thespirit of the invention.

In the accom anying drawings the preferred form o the invention has been shown.

In said drawings-Figure 1 is an elevation of a portion of the hydrocarbon engine and its fuel mixer 4or carbureter, the tanks and the pipe connections being shown diagrammatically. Fig. 2 is a plan view of the parts shown in Fig. 1, the heating mechanism being shown in section; ,v

Referring to the figures by characters of reference A designates the upper portion of or carbureter has been indicated at B. The engine and the carbureter can be of any preferred types and the exhaust pipes C of the en ine open, as ordinarily, into a cylindrical exlausty chamber D from which extends an outlet or exhaust pipe E.

The fuel tank of the mechanism constituting the present invention has been indicated at 1 and this fuel tank is connected by by any suita le mechanism. A valve 4 is arranged in the pipe 2 between the pump A jacket 8 extends around and is spacedv from the exhaust chamber D andv has one or more a1r lnlets 9. A pipe 10 leads from this jacket to the carbureter B. A' pipe 11 isA coiled within the jacket 8 and close to the `exhaust chamber D and one end of its coil is connectedby a pipe 12, to the pump 3, there being a valve 13 within the pipe. The other end of the coil is connectedby a pipe 14to the carbureter B and has a valved drain`15 at itslow'est point while a valve 16 is'located .111 Sald pipe 14 for the purpose of controland the air to be mixed therewith are thor#w 17 between the carbureter and the pipe 19,y la valve 21 within the pipe 18, a valve 22 within the pipe 17 between the tank 1 and the branch plpe 18, and a valve 23 in the branch pipe 19. The pipe 12 is connected by a pipe 24 to the pipe 14 at a point be?A tween the carbureter and the branch pipe 19 and a valve 25 is arranged in this pipe 24,v as shown. A gasolene tank 26 is located at a suitablelpoint above the engine and a pipe 27 extends therefrom and 1s connected to 'pipe 14 at a point between' the carbureter and the pipe 24, there being a valve 28 within said pipe 27 for controlling'the asse-ge of fuel therethrough. A water tan 29 is arranged above the engine A and is connect- Y ed, by `a pipe 30,.to the upper portion of the carbureter and has a valve 31 wherebyv the flow of water through thepipe is controlled.

In using the mechanism described, the supply of water and kerosene is cut off from the carbureter by closing valves 31, 16 and 20. Gasolene is then admitted to the carbureter from the starting tank 26 by opening the valve 28. While the engine is being operated 'for a short time with gasolene as la fuel, the valves 4,13, 22 and 23 are opened,

kerosene or-other fuel' in tank 1, and which' mustl be heated before it can be properly used, will thus be forced by pump 3 through pipe 12 and coil l1 and out through the pipe 14 and branch pipe 19 to pipe 17 and thence back to tank l. As it passes through the coil it will be heated by the gases being ex*- hausted into the chamber D. The fuel is thus continuously circulated by the pump through y the tank 1 and through the coil until said `fuel is properly heated and is in lene as fuel, the coil and pipes are drained at l5 and all of the valves are closed except valves 7, 25, 20 and 21. Surplus gasolene is thus free to How t-hrough the pipe 18 back into the tank 6.

It will be apparent that by equipping a hydrocarbon engine with feeding apparatus such as described, different kinds of fuel may be employed simply by adjusting the various valves so as to cause the fuel to ow `in the proper direction to the carbureter,

the. lighter fuels being admitted directly thereto from the tank while the heavier fuels requiring the application of heat, are directed into the coil 11.

That is claimed is:

1. The combination with a hydrocarbon engine having an exhaust chamber and a carbureter, of means for directing rich fuel into the carbureter to drive the engine, aV

jacket inclosing said exhaust chamber and having an air space therein provided with an outlet, means for conducting heated air from said space to the carbureter, a coil within said space, a fuel tank, a pump for V.circulating fuel through the tank and coil,

to heat the fuel, and separate means for cutting off the supply of rich fuel from the carbureter and directing heated fuel from the coil to the carbureter.

2. The combination with a hydrocarbon engine having an exhaust chamber, and a carbureter, of a jacket surrounding the exhaust chamber, means for conducting air therefrom to the carbureter, a coil within the jacket, the contents of the jacket and of the coil being adapted to be heated by the gases discharged into the exhaust chamber, a fuel supply, a pipe connection between said supply and the coil, a pipe connection between the coil and the carbureter, means for controlling the passage of fuel through said connections, a starting tank, a'valved con* nection between said starting tank and the carbureter, valved means for directing water into the carbureter, and an emergency tank communicating with the fuel conducting connections.

3. Fuel feeding apparatus for hydrocarbon engines, including a tank for fuel to be heated, a jacket for inclosing the exhaust chamber of the engine, said jacket having an air inlet, a coil within the jacket, a second fuel tank, a pump for setting up a circulation of fuel from the first mentioned tank through the coil and back to said tank to vaporize the fuel, valved means for directing the vaporized fuel into a carbureter, means for directing heated air from the jacket and into the carbureter.

In testimony that we claim the foregoing as our own, we have hereto affixed our signatures in the presence of two witnesses.
